Example 1: ALSA works on my X60 laptop, but portaudio on top of ALSA does not. Example 2: Excessive latency compared to using ALSA or OSS directly. > On NetBSD portaudio example that are packaged with portaudio-snapshot work > perfectly.

Under NetBSD and GNU/Linux, I would not recommend using portaudio at this time. It's definitely a work-in-progress on both the portaudio side, as well as our code that uses portaudio. The only reason I built the gr-audio-portaudio tarball is that portaudio works well under certain windows configurations and possibly under OS/X.
